The Malnati family and the invention of Chicago deep dish
The story of Lou Malnati's begins with the broader story of Chicago deep-dish pizza itself, which was reportedly invented in 1943 at Pizzeria Uno, a then-new pizzeria at the corner of Ohio and Wabash in River North. The standard origin story credits Ike Sewell, Pizzeria Uno's founder, with the deep-dish concept; the kitchen execution is generally credited to Rudy Malnati Sr., who managed the pizzeria's kitchen for many years and is widely considered one of the actual originators of the recipe.
Rudy Malnati Sr.'s son Lou Malnati grew up working at Pizzeria Uno alongside his father. By the late 1960s Lou had decided to open his own pizzeria using the family recipe and his own evolving approach to the deep-dish format. The first Lou Malnati's opened in 1971 in Lincolnwood, a Chicago northern suburb. Lou ran the restaurant alongside his wife Jean; the family's commitment to using fresh ingredients, building each pizza to order, and the Buttercrust signature defined the restaurant's identity from opening day.
Lou Malnati died of cancer in 1978 at age 38, leaving Jean to run the business alongside their two sons Marc and Rick (then both teenagers). Marc and Rick took over operations as adults in the 1980s and grew the business from the single Lincolnwood store into the multi-location chain it is today. The family ownership has continued across three generations; Marc and Rick's children are now involved in the business. The Malnati family ethos — quality first, family-run, Chicago-rooted — has remained essentially stable across more than 50 years.
